HMRC on GitHub


Welcome to Her Majesty’s Revenue and Customs (HMRC) on GitHub. Here you can learn about the HMRC Multichannel Digital Tax Platform (MDTP), the citizen and company digital tax services hosted on the MDTP, and the Agile principles and practices that underpin our delivery of the MDTP.

The Multichannel Digital Tax Platform (MDTP)

The Multichannel Digital Tax Platform (MDTP) gives access to digital tax products that allow British citizens and companies to manage their tax affairs. The MDTP is a Platform As A Service (PaaS) that hosts 100+ Scala/Play microservices that represent 20+ citizen and company tax products.

HMRC has a firm commitment to Coding In The Open - developing, testing, building, and releasing code in such a way that the British taxpayer can observe and contribute to progress.
